What’s Steel Plastic Composite Geogrid?
Lianyi® Steel-plastic composite geogrid is made by specially treating high strength steel wires, combining them with polyethylene and adding other additives, and extruding them to form composite high-strength tensile strips,and the surface has a rough texture, it is called a high strength reinforced geogrid. This single band is woven or interlaced at certain intervals in the longitudinal and transverse directions and welded by ultrasonic waves. Due to the product surface being rolled into regular patterns, when laid in the replacement fill soil layer, it bears huge stress resistance and friction with the fill soil. As a whole, it limits the shearing, side extrusion and uplift of the foundation soil. Because the stiffness of the reinforced soil cushion layer is relatively large, it is conducive to the diffusion and more uniform transmission of the upper foundation load to the lower soft soil layer, effectively improving the bearing capacity of the foundation Due to the effect of the reinforced soil cushion layer, the overall stiffness of the foundation within the compression layer range is increased, which is conducive to adjusting the deformation of the foundation. The reinforced soil composite cushion layer formed by using steel plastic composite geogrid is a flexible structure that can absorb the energy of earthquakes very well, so its seismic performance is good.
Steel Plastic Composite Geogrid Features
*It has high strength and low creep,and is suitable for various soil environments.It can be used in tall retaining walls along highways
*It has stable performance,can enhance the interlocking and biting effect of the reinforced bearing surface,strengthen the bearing capacity of the foundation, restrain the lateral displacement of the soil, and increase the stability of the foundation
*It is not easy to be damaged.After the packing is compacted,it is not eroded by ultraviolet light and oxygen,and can meet the requirements of engineering construction
*Corrosion-resistant and long-lasting,steel plastic composite geogrids use plastic materials as the protective layer and are supplemented with various additives to endow them with anti-aging and anti-oxidation properties, and can withstand the corrosion of harsh environments such as acids, alkalis, and salts. Therefore,steel plastic composite geogrids can meet the usage requirements of various permanent projects for over 100 years,and they have excellent performance and good dimensional stability
*The construction is convenient, the cycle is short,and the cost is low.The laying, lapping and positioning of steel plastic composite geogrids are easy, avoiding overlapping and crossing,which can effectively shorten the project cycle and save 10% to 50% of the project cost
*All types support customization.We can customize suitable products according to your needs
Steel Plastic Composite Geogrid Applications
It can be applied to the reinforcement of soft soil foundations,retaining walls and anti-cracking projects of road surfaces in fields such as highways, railways, embankments, abutments, approach roads, docks,revetments,flood control embankments, DAMS, waste dumps, freight yards, airports, sports fields and environmental protection buildings.
